BACKGROUND OF THE INVENTION 1. Field of Invention

This invention relates to technique for recovering hydrocarbon fluids in a process flow; and more particularly to recovering bitumen from a coarse tailings line.

2. Description of Related Art

In a coarse tailings line that goes from a separation vessel (such as a gravity separation vessel or a PSV) to a tailings pond in an oilsands separation plant, trace amounts of bitumen of up to 1% or more may be present in the waste (tailings) line that goes to a tailings pond.

The coarse tailings line is a slurry transport process, which means that water is used to transport the waste to the tailings pond. The waste will include the various sands, clays, water and other natural materials that were separated from the bitumen in the separation plant. In the tailings pond, the solids and sediment settle out, leaving behind the process and naturally occurring water. Any leftover bitumen in the coarse tailings will be discharged to the tailings pond, presenting a potential environmental hazard, as well as a loss of valuable hydrocarbon content.

The pumping of the tailings in the coarse tailings line will cause additional conditioning of the tailings mixture leading to the potential separation of any bitumen in the tailings from the sand and clays in the tailings. This separated bitumen will tend to “float” along the top of the tailings pipe.

One known method to capture the bitumen in the tailings line is to use a skimmer at the very end of the tailings line prior to the tailings pond to skim off the bitumen in the pipe with the use of a diverter plate. The skimmer plate skims off the bitumen and directs it to a tank, with the remaining tailings going to the tailings pond.

The issue with this method is that there is no way to know how much bitumen is present in the coarse tailings line. With a fixed diverter plate, in some instances, too much water will be captured when little bitumen is present, and in other cases, too little bitumen will be captured, with significant amounts of bitumen being directed to the tailings pond.

In view of this, there is a need in the industry to provide a way to know or determine how much bitumen is present in the coarse tailings line. Moreover, there is also a need in the industry to provide a way to capture more bitumen and less water from the process flow, as well as to reduce the amount of bitumen being directed to the tailings pond.

DETAILED DESCRIPTION OF BEST MODE OF THE INVENTION FIG. 1

FIG. 1a shows the apparatus generally indicated as 10 according to some embodiments of the present invention. The apparatus 10 may include one or more of the following: a process pipe having a process flow flowing therein; one or more VF/GVF velocity profile meter 14 configured or arranged on the process pipe 12; diverter apparatus 16 also configured or arranged in relation to the process pipe 12 with a diverter 16 a for selectively diverting some part of the process flow to a tank flow pipe 16 b and the remaining part of the process flow to a tailings pond flow pipe 16 c; and a control processor 20.

The control processor 20 may include a signal processor 20 a configured to: respond to signaling containing information about the presence of a hydrocarbon fluid in a process flow; and determine corresponding signaling to control the diversion of the hydrocarbon fluid from the process flow remaining based at least partly on the signaling received. The signaling containing information about the presence of the hydrocarbon fluid in the process flow may be received, e.g., from the one or more VF/GVF velocity profile meter 14, which determines the presence of the hydrocarbon fluid in the process flow based at least partly on the fluid flow velocity at the various levels or heights sensed within the process pipe 12.

By way of example, the hydrocarbon fluid may include, or take the form of a fluid containing bitumen, including where the process pipe 12 is a coarse tailings line and the fluid contains bitumen flowing in the coarse tailings line. However, the scope of the invention is intended to include determining the presence of other types or kind of hydrocarbons, in other types or kind of hydrocarbon fluids, in other types or kinds of process flows, either now known or later developed in the future.

According to some embodiments of the present invention, the one or more velocity profile meter 14 may be configured with sensors arranged or configured around a circumference of the process pipe 12, consistent with that shown in FIGS. 3a and 3 b.

The signal processor 20 a may be configured to provide the corresponding signaling to a diverter controller 16 d to control the diverter 16 a that diverts the hydrocarbon fluid from the process flow remaining. A person skilled in the art would appreciate and understand how to implement or configure without undue experimentation such diverter apparatus 16 having such a diverter 16 a and diverter controller 16 d in such a process pipe 12 in order to perform the diversion functionality set forth herein consistent with the present invention.

FIGS. 2-7

FIG. 2 shows a process pipe arranged in relation to a holding tank, according to some embodiments of the present invention. The process pipe is shown, by way of example, as a 28″ process pipe, although the scope of the invention is not intended to be limited to any particular dimension thereof. The process pipe may be configured with one or more SONAR-based velocity profile meter, e.g., including a SONARtrac 28″ velocity profile meter that is known in the art and developed by the assignee of the instant patent application. The SONARtrac 28″ velocity profile meter is configured to conform to the 28″ process flow, consistent with that set forth in FIG. 3. The process pipe is also configured with another SONAR-based meter, e.g., including a SONARtrac 28″ VF/VGF meter that is also known in the art and developed by the assignee of the instant patent application. The SONAR-based velocity profile meter and/or SONARtrac 28″ VF/VGF meter may be configured to sense the process flow in the process pipe and provide the signaling containing information about the fluid flow velocity at the various levels or heights within the process pipe.

The inventors have found that in a tailings line containing trace amounts of bitumen, the bitumen at the top of the pipe will transport at a slower velocity than the more dense water in the center of the pipe, but faster than the coarse solids at the bottom of the pipe. Based on this understanding, the SONAR-based 28″ velocity profile meter and/or SONARtrac 28″ VF/VGF meter may be configured to determine the fluid flow velocity at various levels or heights within the process pipe, and provide the signaling containing information about the same. The process flow in whole or in part flowing in the process pipe may be diverted to the holding tank via a skimmer line or to a tailings pond. The skimmer line is shown, by way of example, to be a 6″ skimmer line, although the scope of the invention is not intended to be limited to any particular dimension thereof. According to the present invention, the information about the fluid flow velocity at various levels or heights within the process pipe from the SONAR-based 28″ velocity profile meter and/or SONARtrac 28″ VF/VGF may be used to control the diversion of the hydrocarbon fluid, such as bitumen, from the process flow remaining. In other words, the hydrocarbon fluid, such as the fluid containing bitumen, may be diverted along the skimmer line to the holding tank, while the process flow remaining (substantially not containing the bitumen) may to provided to the tailings pond. In FIG. 2, by way of example, the SONARtrac 28″ VF/VGF is shown configured about 20′ from the diverter point where the process line is coupled to the skimmer line diversion, and the skimmer line diversion is configured about 60′ from a 6″ VF/VGF configured to provide a further measurement of the diverted hydrocarbon fluid flowing in the skimmer line to the holding tank. In FIG. 2, the skimmer line is understood to be configured with appropriate diverter apparatus at the diverter point having a skimmer consistent with that set froth in relation to FIG. 1a herein.

In FIG. 2, the holding tank is configured to receive the diverted hydrocarbon fluid, such as fluid containing bitumen, to provide water to the tailings pond, and also to provide recovered hydrocarbon, such as bitumen, to a CEDA VAC truck pump to barrels, as shown. The barrels containing the recover hydrocarbon, such as bitumen, may be transported so that the recovered hydrocarbon, such as bitumen, may be appropriately used or sold as needed in the marketplace.

FIGS. 3a and 3b shows an implementation of the velocity profile meter, having sensors arranged or configured around the circumference of a process pipe, so that the fluid flow velocity at various levels or heights within the process pipe can be determined. For example, in a horizontal process pipe that contains a flowing slurry of liquid and solids, because of gravity and density effects, the solids will tend to flow along the bottom of the pipe and liquids will tend to flow along the middle and top of the pipe. In FIGS. 3a, 3b , by way of example, the velocity profile meter may be, or take the form of, a wrap-around velocity profile meter that uses multiple sensing arrays, including where the multiple sensing arrays are located radially at a top position of 0°, a bottom position of 180°, and intermediate positions 45°, 90° and 135°.

FIG. 4 includes a graph that shows a typical expected velocity profile of a slurry containing a combination of solids (such as sand and clays) with water flowing in a process pipe. The graph in FIG. 4 shows the slower moving solids at the bottom of the process pipe, with faster moving water near the top of the process pipe. The vertical axis represents the nominal pipe height, the horizontal axis, and the velocity.

It is understood that in a process pipe that contains a combination of solids (such as sands and clays) with water and bitumen, the bitumen will tend to “float” to the top of the process pipe and move at a slow velocity than the water in the center of the process pipe, but at a faster velocity than the solids at the bottom of the process pipe. FIG. 5 includes, by way of example, a graph that shows an example of a process pipe containing solids, water and bitumen.

FIGS. 6 and 7 include, by way of example, graphs that show a velocity profile at the beginning, middle and end of a coarse tailings line.

According to some embodiments of the present invention, and consistent with that disclosed herein, the velocity profile meter may also be used to detect a stationary sand bed forming in a pipe, leading to a sand-out or clog of the pipe.

The present invention may include the diverter controller 16 d (FIG. 1a ) to be used to control a diverter 16 a arranged in the process pipe, such as process pipe 12. The diverter 16 a may include, or take the form of, a fixed diverter. In the case of the fixed diverter, the pipe connecting the fixed diverter 16 a to a holding tank can be closed off when no bitumen is detected, and opened when bitumen is detected.

Alternatively, the diverter 16 a may include, or take the form of, a variable diverter. The variable diverter can be utilized, and the position of the diverter adjusted, based upon the detected amount of bitumen in, e.g., the coarse tailings line. For example, the velocity profile meter or system can be used to optimize bitumen recovery in a closed-loop fashion with an adjustable skimmer blade that will adjust to the levels and degree of bitumen separation in the process pipe as indicated by the velocity profile meter.

While the present invention is shown and described for use in a coarse tailings line, the present invention may be used in any process where there is the possibility of a flow containing solids, water and hydrocarbon fluids, to detect the presence of the hydrocarbon fluid, and also, if desired, control the diversion of the hydrocarbon fluid from the remaining flow using a skimmer or some other method or technique.

In a typical software implementation, the signal processor 20 a may be, or take the form of, one or more microprocessor-based architectures having a microprocessor, a random access memory (RAM), a read only memory (ROM), input/output devices and control, data and address buses connecting the same. A person skilled in the art would be able to program such a microprocessor-based implementation to perform the functionality set forth in the signal processor 20 a, as well as other functionality described herein without undue experimentation. For example, a person skilled in the art would be able to program such a microprocessor-based implementation without undue experimentation for the implementation of the control processor 20 and the signal processor 20 a to respond to the signaling containing information about the presence of the hydrocarbon fluid in the process flow; and determine the corresponding signaling to control the diversion of the hydrocarbon fluid from the process flow remaining based at least partly on the signaling received, consistent with that disclosed herein. Moreover, a person skilled in the art would be able to program such a microprocessor-based implementation without undue experimentation for the diverter controller 16 d to respond the corresponding signaling and control the diverter 16 a and the diversion of the hydrocarbon fluid from the process flow remaining based at least partly on the corresponding signaling received, consistent with that disclosed herein. The scope of the invention is not intended to be limited to any particular implementation using technology now known or later developed in the future. Moreover, the scope of the invention is intended to include the signal processor being a stand alone module, as shown, or in the combination with other circuitry for implementing another module.

It is also understood that the signal processor 20 a may include one or more other modules, components, circuits, or circuitry 20 b for implementing other functionality associated with the apparatus that does not form part of the underlying invention, and thus is not described in detail herein. By way of example, the one or more other modules, components, circuits, or circuitry generally indicated as element 20 b may include random access memory, read only memory, input/output circuitry and control, data and address buses for use in relation to implementing the signal processing functionality of the signal processor 20 a.
